It fixes a crash in CodeGen when we are trying to generate code for
initializer expression created before template instantiation, like
CallExpr '<dependent type>'
|-UnresolvedLookupExpr '<overloaded function type>' lvalue (ADL) = 'parse'
`-DeclRefExpr 'Buffer<N>' lvalue ParmVar 'buffer' 'Buffer<N>'
